Numerical Simulation of the Howard Street Tunnel Fire, Baltimore, Maryland, July 2001

K. B. McGrattan / A. Hamins

This report documents a study undertaken to estimate the thermal environment of the Howard Street Tunnel in Baltimore, Maryland, following the derailment in July 2001 of a freight train and the burning of spilled tripropylene and the contents of surrounding rail cars. A numerical fire model developed by the National Institute of Standards and Technology (NIST) has been used to simulate the fire's growth and spread in the tunnel. The fire model has been validated for this application using temperature data collected during a series of fire experiments conducted at a decommissioned highway tunnel in West Virginia. The cross-sectional area of the tunnel and the fire sizes used in the West Virginia experiments are similar to the Howard Street Tunnel.
